Use HikariCP to significantly improve performance

purpose

Yesterday, Druid was replaced with the stable version of C3P0;
highly recommended by old friends, the use of HikariCP greatly improved the database connection performance;

The final result:
Concurrent 2000 pressure test, c3p0 opened 2000 threads; HikariCP only opened 120 threads!

1. Modify Pom.xml and introduce HikariCP dependency

<dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP</artifactId>
</dependency>

2. Modify applicaton.yml

spring:
  application:
    name: nh-tst
  http:
    encoding:
      charset: UTF-8
      enabled: true
      force: true
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    driver-class-name: oracle.jdbc.driver.OracleDriver
    url: jdbc:oracle:thin:@xxxxxx:1522/prodpdb1
    username: xxxxx
    password: xxxxx
    hikari:
      pool-name: FxdDbPool
      minimum-idle: 10
      idle-timeout: 600000
      maximum-pool-size: 300
      auto-commit: true
      max-lifetime: 1800000
      connection-timeout: 180000

Finally, I sighed: A big copy on the Internet, this configuration has been found in 5 blogs and checked for various errors.

It is not easy to be original, and cherish it!
